Viteza freza ?

Recommended Posts

Buna ziua.

 

Vreau sa adresez o intrebare. Care este viteza optima de folosire a unei freze pentru ca aceasta sa nu se rupa.

 

Va intreb deoarece am reusit azi sa rup o freza canelata de la Bosch de 3mm HS/CT intr-o placa de pal.

Frezarea a fost facuta la 6mm adancime deci nu a fost adanca.

 

Treaba a fost ca am facut canalul de 3mm si pe urma am vrut sa l largesc la 5mm si a crapat freza.

Viteza la router a fost cam 3.5 pe scala de 1-6(11-28.000 rotatii) si pe freza scrie 35.000.

 

Acuma habar nu am de ce s-a rupt ca nu am fortat la impins. Daca are cineva vreo idee motivul ruperii si sa imi spuna si la ce viteza trebuie folosita, mica, mare, medie ?

 

Cei de la Bosch au ramas f surprinsi au zis ca nu am mai intalnit asa ceva sa se rupa freza.

Viteza ca viteza, da' avansul cat a fost?

Avansul a fost incetisor, nu am fortat.

Primul canal de 3mm a mers super pe cei 2metri. La largire pana la 5mm am impins freza cam vreo 30cm si s-a rupt varful.
